摘要： An arrangement for the transmission of magnetic resonance signals that are received with the aid of local coils is provided. The magnetic resonance signal is fed to an analog/digital converter and digitized by the analog/digital converter. The magnetic resonance signal is compressed in amplitude before being fed to the analog/digital converter, is low-pass filtered or band-pass filtered, and is expanded after digitization by the analog/digital converter. A clock rate that is higher by a factor 2n than a sampling rate n of the analog/digital converter (ADC) is used for the digital expander. A digital equalizing filter for compensating for a filter transmission function in a transition range may also be used.

摘要： In a magnetic resonance tomography local coil arrangement and a method for processing signals received thereby, at least one local coil is fashioned to receive at least one reception signal and at least one amplifier is provided that amplifies the at least one reception signal. A frequency converter generates at least one intermediate frequency signal from the at least one reception signal the intermediate frequency of the intermediate frequency signal differing from the reception signal frequency of each reception signal. An analog-digital converter converts the analog intermediate frequency signal into a digitized signal. A shielding device shields against at least radio-frequency signals, the shielding device surrounding at least the analog-digital converter. At least one frequency filter is arranged between the at least one local coil and the analog-digital converter, the frequency filter exhibiting a transmission range for signals with the intermediate frequency of an intermediate frequency signal. The digitized signal is transmitted from the local coil arrangement.

摘要： In a method for processing radio frequency signals of a magnetic resonance imaging system in which the coil portion of the magnetic resonance imaging system includes a body coil and a local coil, radio frequency signals are supplied to the body coil, and these radio frequency signals are coupled to said local coil, and transmitted by said local coil into a region to be examined. A corresponding radio frequency system has a local coil and a body coil, with power coupling between the local coil and the body coil; during the phase for transmitting the radio frequency signals. The body coil serves to couple the radio frequency signals to be transmitted to the local coil, and the local coil serves to transmit the coupled radio frequency signals to a region to be examined. This method and system allow the transmitting function of the local coil to be achieved without having a coil plug on a patient bed to provide a radio frequency signal transmitting channel.

摘要： An arrangement to transmit magnetic resonance signals has at least two reception branches. Each reception branch contains a single antenna of a local coil as well as an amplifier connected with the single antenna, such that an amplified magnetic resonance signal is formed from a magnetic resonance signal that is acquired via the single antenna. In a multiplexer, each input is connected with a respective reception branch, such that the amplified magnetic resonance signals of the reception branch are combined by the multiplexer into a resulting signal using a time multiplexing method. A transmission path is connected on one side with an output of the multiplexer and on the other side with a receiver, such that the resulting signal is transmitted from the multiplexer to the receiver via the transmission path.

摘要： A circulator has a ferrite, and the circulator is arranged in the vicinity of a device that produces a static magnetic field in the environment surrounding the device, this static magnetic field giving the circulator a non-reciprocal behavior, with respect to circulation of energy among the gates of the circulator, as a result of interaction of the ferrite with the static magnetic field. A magnetic resonance apparatus embodies such a circulator, and the basic field magnet of this magnetic resonance apparatus generates the static magnetic field.

摘要： In a method and device for the transmission of a multiplicity of signals having different frequencies between a base station and a module situated at a location remote from the base station via a single, common cable connection, some of the signals being transmitted from the electronic assembly to the module and, in general simultaneously, the remaining signals are transmitted in the opposite direction. Each of the base station and the module has bandpass filter bank therein having a multiplicity of bandpass filters, the number thereof being a function of the number of channels to be transmitted, with which the respectively received signals are spectrally separated from one another so that they are available for further signal processing in the base station, or for further use in the module.
